Boxplot, formula interface, and labels.
Just change the separator: data(Titanic) Titanic.df <- as.data.frame(Titanic) boxplot(Freq~Class*Sex, Titanic.df, cex.axis=.6, sep="\n") See attached .png. ---------------------------------------- David L Carlson Department of Anthropology Texas A&M University College Station, TX 77843-4352 -----Original Message----- From: R-help [mailto:r-help-bounces at r-project.org] On

Boxplot, formula interface, and labels.
I have data I'd like to plot using the formula interface to boxplot. I call boxplot like so: with(mydata, boxplot(count ~ geno * tissue)) I get a boxplot with x axis labels like "wt.kidney". I would like to change the '.' to a newline. Where is this separator configured? Thanks, -Ed

ggplot inside function doesn't plot
I don't really understand. I mean, I understand the solution is print(ggplot(...)). But why is that required in a function and not at the console? Shouldn't I be able to rely on what I do at the console working in a script? Is this inconsistent behavior by design?

Exporting to text files
I have dose response data analyzed with the package 'drc'. 'summary(mymodel)' prints my kinetic parameters. I want that text in an ASCII text file. I want to get exactly what I would get if I copied and pasted from the terminal window. I've read the documentation on data export to text files here:

lists and rownames
I'm doing some string manipulation on a vector of file names, and noticed something curious. When I strsplit the vector, I get a list of character vectors. The list is numbered, as lists are. When I cast that list as a data frame with 'as.data.frame()', the resulting columns have names derived from the original filenames. Example code is below. My question is, where are these names

data.matrix output is not numeric
I have a data frame full of integer values. I need a matrix full of numeric values. ?data.matrix reads: Return the matrix obtained by converting all the variables in a data frame to numeric mode and then binding them together as the columns of a matrix. This does not work. test.df <- data.frame(a=as.integer(c(1,2,3)), b=as.integer(c(4,5,6))) > class(test.df[[1,1]]) [1]

How to alpha entire plot?
I have two chromatograms I want plotted on the same axes. I would like the plots to be transparent, so the first chart is not obscured. I have tried adjustcolor(..., alpha.f=0.3), the problem is that my chromatogram is so dense with datapoints that they overlap and the entire graph just ends up a solid color. The second histogram still obscures the first. Consider this example: col1 <-

svm
Hi, I understand from help pages that in order to use a data set with svm, I have to divide it into two files: one for the dataset without the class label and the other file contains the class label as the following code:- library(e1071) x<- read.delim("mydataset_except-class-label.txt") y<- read.delim("mydataset_class-labell.txt") model <- svm(x, y, cross=5)

readDGE: Error in colnames/length of dimnames not equal to array extent
Hello, all, I''m a new R user (new to any programming language in general, really), so I apologize if this is easy/has already been answered (I''ve attempted searching online but did not understand the pages I found).

importing data to SQLite database with sqldf
Hi all, I am attempting to learn SQL through sqldf... One task I am particularly interested in is merging separate (presumably large) files into a single table without loading these files into R as an intermediate step (by loading them into SQLite and merging them there). Taking a step back, I''ve considered these alternatives: 1) I know if I use straight SQLite commands I might use

change all . to 0 in a data.frame
Hello, I read in a tab delimited text file via mydata = read.delim(myfile). The text file was originally an excel file where . was used in place of 0. Now all the columns which should be integers are factors. Any ideas how to change all the . to 0 and factors back to integer?
